Pendulum motion approximates SHM provided

• the length of the pendulum is short

• the length of the pendulum is long

• the angle of swing is small

• the angle of swing is large

A pendulum is released and a timer is started at the same time. The best formula for displacement will be

• y = A Sin ωt

• y = A Cos ωt

• y = - A Sin ωt

• y = -A Cos ωt

A mass is hung from spring, pulled down and released. The best formula for displacement against time is

• y = A Sin ωt

• y = A Cos ωt

• y = -A Sin ωt

• y = -A Cos ωt

A pendulum is pulled to one side and released. The best formula for speed against time is

• y = A Sin ωt

• y = A Cos ωt

• y = -A Sin ωt

• y = -A Cos ωt

An object is performing vertical SHM. X represents a position on its reference circle. Which point on the graph corresponds to X ?

• A

• B

• A or B

• C o D

A mass is oscillating on a spring. Position X represents the point of

• maximum speed

• maximum downward acceleration

• maximum upward acceleration

• minimum displacement

The graph shows the reducing amplitude of a body in SHM. This is known as

• dumping

• damping

• wetting

• doodling
